Abstract
A screening procedure was developed for the determination of 49 priority pollutants in soil. An extraction procedure followed by the capillary gas chromotographic technique was used. Dual pH solutions with methylene chloride were used as extraction solvent system; no sample clean‐up procedure was applied. Both base/neutral and acidic fractions were analyzed on the same capillary column (SPB‐1). The relative standard deviation for 5.1 ppm (51 μg/ 10 g) concentration in “zero soil” was less than 25%.
